For all XenApp admins and consultants out there Project Avalon will bring a big change as we are used to having XenApp servers running on the (what seemed to be) everlasting Citrix Independent Management Architecture and we’re heading to Citrix FlexCast Management Architecture (already included in XenDesktop at this moment) and will be included in the Citrix Excalibur Architecture.

I recently build a Citrix XenApp 6 deployment using RES Automation Manager but encountered problems with some (not all) installations. After a default installation the IMA service couldn’t start. When looking at the eventlogs of one of those specific servers I found the following errors:
Failed to load plugin C:\Program Files (x86)\Citrix\System32\Citrix\IMA\SubSystems\ImaAppSs.dll with error IMA_RESULT_WRITE_TO_LOG_FAILED
Failed to load initial plugins with error IMA_RESULT_WRITE_TO_LOG_FAILED
and further on in the eventlog the following error was presented:
When searching on the internet I found the following fix:
Well apparently this is a Citrix common item because the Citrix tech went straight to this registry key and changed it.
Then blanked out the following keys:
After that, IMA magically starts and all services come back up and running.
So based on this I took one of the XenApp 6 servers and blanked those keys:
After this I could start the IMA service again and I was able to launch a published desktop on this server again.
